# BetBuddyRank

> BetBuddyRank is an independent leaderboard of tipsters on X (formerly Twitter). We take public sports picks posted before kick-off, link each pick to a specific match and grade it against the final score. For every tipster we compute the hit rate, the expected hit rate from odds and team strength, ROI and an index that accounts for how hard the picks were. The leaderboard is recalculated automatically after every results update and covers football (soccer), NFL, MLB, tennis, basketball and hockey.

The site is available in English (https://betbuddyrank.com/en) and Russian (https://betbuddyrank.com/). Every pick links to the original public post on X and to the final score. BetBuddyRank is not affiliated with X Corp. or any sportsbook and is not betting advice (18+).
